MC4558 Wide Bandwidth Dual Operational Amplifier

Contents hide

MC4558 is a high-performance monolithic dual operational amplifier. The circuit combines all the outstanding features of the MC1458 and, in addition, possesses three times the unity-gain bandwidth of the industry standard. The IC is constructed using gated P-channel MOSFET at the input; so, as to provide a very high input impedance. The IC has a wide range of working voltages and directly interfaces with both passive and active electronic components; making it ideal to be used with any device.

Operational Amplifiers

An operational amplifier or op-amp is simply an electronic linear Integrated Circuit or IC that has multiple terminals. An op-amp is a voltage amplifying device that is meant to be work with external feedback components such as resistors and capacitors. Operational amplifiers are considered to be one of the most vastly used electronic component, with applications ranging from small scale consumer electronic components such as smartphones, tablets, PCs, to large scale industrial instrumentation tools such as poisonous gas sensors and transducers for impurity detection.

There are two main classifications of amplifiers:

Inverting Amplifiers
Non – inverting amplifiers
